Heat resistant steel, especially for use in the electrical power generating, nuclear and chemical industries, has a ferritic or tempered martensitic structure with palladium- and-or platinum-containing intermetallic compound phases

摘要

A heat resistant steel, having a ferritic or tempered martensitic structure containing uniformly dispersed precipitated intermetallic compound phases of specified structure, is new. A heat resistant steel has a ferritic or tempered martensitic structure containing a uniform dispersion of precipitated intermetallic compound phases of L10 or L12 ordered structure.
